Chapter 13 Flashcards
Transport from plasma membrane and between golgi and endosomal compartments
Clathrin
Transports from golgi to ER
COP1
Coates vesicles transports from ER to Golgi
COPII
What is the inner coat made of
Sec 23
Sec 24
What is the outer coat made of
COPII
Only present when going from plasma membrane to inside the cell; insert loops from cytosolic side helps stabalize curvature of membrane
Caveolin
When AP2 binds to cargo receptors what does it recruit
Clathrin
What protein is involved in COPII assembly and adaptor proteins sec23 &24
Sar-1
What directs vesicles to correct place
Rabs
Mediates fusion of lipid layers
SNARE
This snare is is a vesicle single polypeptide chain
V snare
This snare target membrane made of 3 proteins
T snare
What happen in Golgi
Proteins get processed and packaged to send them to there destinations
This part of the golgi is where proteins and lipids enter through this network
cis golgi
This part of the golgi is where proteins and lipids leave through
Trans golgi
Type of coat involved in vesicle formation from ER to golgi
COPII
What is the function of lysosomes
Digest macromolecules
How does the lysosomes maintain a low pH
H+ ions are pumped into it by H+ atpase
What kind of enzymes are part of the lysosomes
Hydrolytic enzymes
When are the lysosomes enzymes active
At an acidic pH
What are the type of signal present on proteins to be transported from the trans golgi to lysosomes
Mannose 6 phosphate
What type of coat is involved in the cargo of proteins from trans golgi to lysosomes
Clathrin
This transport involves engulfing matter to form a phagosome on the inside
Phagocytosis
Cells ingesting fluid into the memebrane
Pinocytocis
The cell ingesting large amounts of fluid into cell
Macropinocytosis
